I have a Victor cutting head that does something strange. After the
flame starts,a little explosion follows and the flame extinguishes. I
do not want to go too far in troubleshooting this before asking for
advice, so, any ideas will be appreciated.

Has it done this with more than one cutting tip? It could be a nick on the
seating/sealing surface, either the tip or the torch. If it happens with
more than one tip, it's prolly the torch.
The simple solution is to change the tip.
If the tip is not sealing properly it will cause popping.
If the tip is not the problem then you have a leaking oxygen valve seat.
It has to be repaired by a torch repair shop.
I love Victor torches, but their "achilles heal" is the fact that since
they are a body mixed torch, if the gasses in the mixing chamber
ignite, the back pressure will erode the oxygen valve seat.
Once the valve seat is eroded, the popping will get worse.
Torches that have 3 tubes going to the head are "TIP mixed" torches and
don't suffer this problem.
2 tubes means body mixed.
Torches like Airco, Rego, Smith, Marquette and Concoa are TIP mixed.
Victor, Harris, Purox, Oxweld and Meco are Body Mixed

I might argue about the Harris design which incidentally seems to be an
obsolete oxweld design form perhaps 50 years ago in that the mixer or
injector is very near the tip and not anywhere near the handle. I consider
it a hybrid design. I believe Harris made/makes eutectic and Marquette
There also is the possibility that the mixer in the torch in question is not
an acetylene one. Or the tip for that matter. Often extreme tightening
of the nozzle nut will suffice. usually that is the issue, if the torch in
question comes apart so as to using welding heads perhaps the seating there
should be checked as well.
All three of my Harris torches are 3 tubed
